高分辨率扫描隧道显微镜显示，在Au(111)表面15冠5联酞菁阵列的四个冠醚部分中，只有对角位置的两个冠醚空隙，其中空隙中心与三个金原子包围的空心完全匹配，捕获了两个Ca2+离子。
High-resolution scanning tunneling microscopy has revealed that, of the four crown-ether moieties of 15-crown-5-ed phthalocyanine array on Au(111) surface, only two crown-ether voids at diagonal positions, where the void centers and hollows surrounded by three gold atoms match exactly, trap two Ca2+ ions.
